I'm sure everyone's heard of stories where a guy meets a girl, and the more they spend time together the more he can't stop thinking of her. It's almost like torture, as thoughts of her don't leave his mind day and night, until he realises that his infatuation can only be relieved by an outpour of emotions in her presence -- whether subtly, or in some instances...like a frantic animal.
It's clear that almost every man goes through that. But how often do girls experience this? Does this happen at all? Cause I've never really heard of a girl being so obsessed, nor approaching her "man of interest" in this way.
